Synthesis, molecular modeling and biological evaluations of novel pyrrolidine derivatives as potential cyclooxygenase-2 (COX-2) inhibitors

Toward the development of selective cyclooxygenase-2 inhibitors, a series of pyrrolidine derivatives is described. All the compounds containing sulfonamide, ester, nitrile, acid, amide and urea functionalities were computationally screened, and binding affinity scores for all synthesized compounds with cyclooxygenase-1 and cyclooxygenase -2 were compared. The computational observations showed three top-ranked compounds (8b, 8d and 10a) having selectively more affinity for cyclooxygenase -2. These were selected for pharmacological evaluation using carrageenan-induced rat paw edema model. Compound 8b showed maximum activity (54.83%) which was closer to standard drug indometacin (57.48%). The safety parameter of the potent compound (8b) was assessed using aspirin induced gastric ulceration animal model. [GRAPHIC].

One-pot synthesis of pyrrolidones from levulinic acid and amines/nitroarenes/nitriles over the Ir-PVP catalyst

The synthesis of pyrrolidones via reductive amination of levulinic acid with aniline was examined over polypyrrolidone-stabilized metal nanoparticle catalysts. Among them, Ir metal was the most effective and applicable for the reductive amination of levulinic acid with nitroarenes/nitriles. Importantly, this catalyst was used for the one-pot synthesis of the anti-inflammatory drug indoprofen from 2-formylbenzoic acid and 2-(4-nitrophenyl)propanoic acid.

Failure analysis of LiNi0.83Co0.12Mn0.05O2/graphite-SiOx pouch batteries cycled at high temperature

The combination of Ni-rich layered oxide and graphite-SiOx is regarded as a high-energy-density system for the lithium-ion power batteries. It is significant to elaborate the failure mechanism of the two materials in full batteries, especially at high temperature. In this study, the failure behavior of LiNi0.83Co0.12Mn0.05O2/graphite-SiOx pouch batteries (>= 50 Ah) cycled at 45 degrees C has been studied by using the non-destructive electrochemical methods and physico-chemical methods for the cathode and anode materials. Compared with the failure mechanism of lithium-ion batteries cycled at room temperature, it is more inclined to occur at high temperature that transition metal ions dissolve out from cathode and deposit on the anode, electrolyte decomposes, and solid electrolyte interphase grows. The resulting phenomena show that the cathode deterioration is slight, and the anode degradation is the main factor of pouch battery degradation. After failure analysis, the concentrationgradient NCM cathode and nitrile-containing electrolyte additive are assembled into the pouch batteries, and the capacity retention increases from 75.24% (pristine batteries at 280 cycles) to 83.44% (improved batteries at 1500 cycles). Therefore, we suggest that power batteries operating at high temperature should be with minimized transition metal dissolution of cathode materials and stable solid electrolyte interphase.

Quantum chemical study on the formation of isopropyl cyanide and its linear isomer in the interstellar medium

The formation mechanism of linear and isopropyl cyanide (hereafter n-PrCN and i-PrCN, respectively) in the interstellar medium (ISM) has been proposed from the reaction between some previously detected small cyanides/cyanide radicals and hydrocarbons/hydrocarbon radicals. n-PrCN and i-PrCN are nitriles therefore, they can be precursors of amino acids via Strecker synthesis. The chemistry of i-PrCN is especially important since it is the first and only branched molecule in ISM, hence, it could be a precursor of branched amino acids such as leucine, isoleucine, etc. Therefore, both n-PrCN and i-PrCN have significant astrobiological importance. To study the formation of n-PrCN and i-PrCN in ISM, quantum chemical calculations have been performed using density functional theory at the MP2/6-311++G(2d,p)//M062X/6-311+G(2d,p) level. All the proposed reactions have been studied in the gas phase and the interstellar water ice. It is found that reactions of small cyanide with hydrocarbon radicals result in the formation of either large cyanide radicals or ethyl and vinyl cyanide, both of which are very important prebiotic interstellar species. They subsequently react with the radicals CH2 and CH3 to yield n-PrCN and i-PrCN. The proposed reactions are efficient in the hot cores of SgrB2 (N) (where both n-PrCN and i-PrCN were detected) due to either being barrierless or due to the presence of a permeable entrance barrier. However, the formation of n-PrCN and i-PrCN from the ethyl and vinyl cyanide always has an entrance barrier impermeable in the dark cloud; therefore, our proposed pathways are inefficient in the deep regions of molecular clouds. It is also observed that ethyl and vinyl cyanide serve as direct precursors to n-PrCN and i-PrCN and their abundance in ISM is directly related to the abundance of both isomers of propyl cyanide in ISM. In all the cases, reactions in the ice have smaller barriers compared to their gas-phase counterparts.

Regioselective Transition-Metal-Free Synthesis of 2-(Trimethylsilylmethylene)pyrrol-3-ones by Thermal Cyclization of Acetylenic Enamines

Acetylenic enamines generated in situ from readily available enynones and primary amines undergo thermal cyclization in diphenyl ether providing easy access to 4-aryl-2-(trimethylsilylmethylene)-1,2-dihydro-3H-pyrrol-3-ones. This reaction is inherently versatile, allowing for variations of substituents in both enynone and amine. Full regioselectivity along with short reaction time (1-2 h) and simple workup afford single products in good to excellent isolated yields. Fluorescent properties of the obtained compounds were studied.
